A material designed to repair dental prostheses that consists of an unfilled polymeric resin. The material works as a bonding agent to provide a strong and long-lasting attachment to the segments of a broken or cracked prosthesis; it typically consists of a single or two-component polymeric (e.g., acrylic) resin that usually becomes a solid polymer when treated with light and/or heat. The material is used in a dentist?s office or dental laboratory to repair fixed dental prostheses and/or partial or total dentures.
